Long-period steady-state anesthesia mixture for laboratory mice

The invention relates to an anesthetic for experimental animals, and belongs to the field of medical drugs. The invention discloses a long-period steady-state anesthesia mixture for laboratory mice. The long-period steady-state anesthesia mixture comprises the following components: a compound 1, a compound 2 and a compound 3. According to the technical scheme, an excellent anesthetic effect is achieved on rodent mice (especially immunodeficient mice) by utilizing the existing non-controlled anesthetic and mixing proportion, and thousands of surgeries prove that the anesthetic is stable in mouse abdominal cavity surgeries and mouse cranial cavity surgeries and does not cause mouse death. The problem that in the current experimental animal field, especially in the mouse experimental field, anesthetic drugs are difficult to purchase and approve can be well solved. Moreover, the anesthetic is small in injection dosage (0.1 ml/20g), small in influence on operation and small in side effect on animals, the anestheti
